digitalmars.D.learn - Integrate Platform SDK with << D >> language

I just download Platform SDK and D Compiler.
I have GCC/G++ 3.4 Compiler from Cygwin.
I need to know what header files/packages/include files are available for D
Compiler.
Without manually demangaling the prototypes available in the PSDK how do I
access them all the from << D >> language.
I have been working on Java/C/C++/JavaScript, a bit of Python,PHP,ASM.
Please help.
